摘要：
Shearography is an interferometric method for the direct measurement of derivatives of surface displacement. Shearography is traditionally practiced with a double-exposure mode. This paper presents a realtime technique which allows the derivative of surface displacement of the test object to be continuously observed. This technique is useful for monitoring time-dependent or transient deformation.
